Polymer materials and spring: Premier Li Keqiang visits the first station of Sichuan "graced" polymer


April 25, 2016, the CPC Central Committee Political Bureau Standing Committee, Premier Li Keqiang came to Sichuan University to study work.

The prime minister was the first one to reach the State Key Laboratory of polymer materials engineering, visited the laboratory independently developed the world's first graphene rubber tires, the first domestic haemodialysers, lithium battery separator sets new technology achievements. He encouraged researchers to speed up the transformation of achievements.

Development of polymer materials

Polymer materials, including plastics, rubber, fiber, films, adhesives and coatings, etc.. Among them, the plastic, synthetic fiber and synthetic rubber, which are known as the three major synthetic materials of modern polymers, have become the indispensable material for the national economic construction and people's daily life.

In 1839, the American Goodyear invented the vulcanization of natural rubber.

In 1855, the British Parks prepared the match Lu Lu plastic (nitrocellulose camphor).

In 1869, American John · a special match haia Lu Lu products.

In 1883, the French Chardonnet de invented the artificial silk.

1896, artificial silk industrialization.

1909, Baekeland synthetic phenolic resin.

1911, Mathews laboratory synthetic polystyrene.

In 1912, synthetic polyvinyl chloride.

Polystyrene (POLYSTYRENE) laboratory synthesis, 1920.

In 1925, polyvinyl acetate industrialization.

In 1927, poly (methyl methacrylate) (PMMA) and polyvinyl alcohol were published.

1931, PVC PVC industrialization and the advent of chloride butyl rubber.

1933, high pressure polyethylene.

1934, polystyrene (PS) industrialization.

In 1935, Caro Sass's nylon -66 came out and realized industrialization in 1938.

In 1938, the laboratory of polymerization of tetrafluoroethylene.

1939, low density polyethylene (LDPE) industrialization.

1940, styrene butadiene rubber and butyl rubber.

In 1941, polyethylene terephthalate (PET, polyester) came out.

1943, PTFE (PTFE) industrialization

1947, silicon semiconductor.

1948, the advent of Vigny lun.

In 1950, polyacrylonitrile (Pan, PAN) published

1953, polyester PET industrialization.

In 1953, Ziegler on the condition of low pressure polyethylene synthesis, then synthesized Natta polypropylene.

In 1955, the advent of butadiene rubber.

Silicon integrated materials, 1957.

In 2000, the volume of polymer products (plastic, rubber, chemical fiber) accounted for the first.

Study on the polymer materials in China started in the early 1950s, the polymer chemistry, polymer physics, polymer processing and polymer reaction engineering and industry cooperation, has developed a number of polymer materials and production technology. At present, China's plastic resin production ranks fourth in the world, plastic machinery is the largest producer, the total output of plastic products exceeded second tons ranking 20 million in the world, China has entered the ranks of the world's largest plastic. China's plastics industry is one of the last few years the rapid pace of development of the industry, the growth rate has remained above 10%, synthetic resin and plastic additives, plastic processing machinery and moulds, plastic processing and application of the three pillar industries have increased.
